C++ Break Statement
The C++ break statement is used to exit a loop prematurely. It is typically used in for, while, and do-while loops to terminate the loop before the loop condition is met.
Here’s an example of using the break statement in a for loop:
C++
#include <iostream>
int main() {
for (int i = 1; i <= 10; ++i) {
if (i == 5) {
break; // Exit the loop when i equals 5
}
std::cout << i << " ";
}
std::cout << std::endl;
return 0;
}Output:

You can also use break in while and do-while loops:
C++
#include <iostream>
int main() {
int i = 1;
while (i <= 10) {
if (i == 5) {
break; // Exit the loop when i equals 5
}
std::cout << i << " ";
++i;
}
std::cout << std::endl;
return 0;
}Output:

++i;
} while (i <= 10);
std::cout << std::endl;
return 0;
